There have been serious problems here in the past but access appears less problematic providing climbers keep a low profile. The quarries are owned by Gwynedd Council who make it clear that there is no offical access due to public safety reasons - there are high fences and signs prohibiting access, but there have not been any reports of practical access problems for many years.
In early 2017 planning permisson was granted for a new hydro-electric power station on the site. When works starts on this (unkknow time-scale) its likley that access to some of the quarries will be permenently lost, especially to Mancer and Film Set Quarries as these will become flooded to produce a holding reservoir.
